“Bitcoin implicates the First Amendment. As a system for collecting and communicating information ranging from payment data to art, #bitcoin is speech. As a statement of protest against the government’s monopoly over money, bitcoin is expressive conduct. And as a collection of individuals that share bitcoin’s hard-coded principles of individual liberty, anti-censorship, and anti-debasement, bitcoin is an expressive association.Bitcoin is free speech protected by the First Amendment and therefore regulating bitcoin has clear constitutional implications."
